The same thought has crossed my mind on the tcase xmember. I'll probably accomplish the stiffening by welding tented angle along the length.

I would think that would work.

If I see weakness at the brackets, I'll definitely hit you up for that 3" tube. Sounds nice!

Yeah, I was rebuilding a Taco elocker axle housing. The spring perches are pretty notorious for collapsing into the housing itself, from axle wrap, and these were no exception. So I came up with the idea of thicker tube that would be just inside the U bolts, but wrap the axle and carry the force and dissipate it over a larger area. Should be hell for stout.

Keep an eye out for dimpling where your brackets mate with the axle housing, and if it starts the thicker HREW should make it mondo beefy. The only downside is, *careful* stitch welding is mandatory or you will warp your axle housing for sure.

The lowers are about at the centerline of the axle, so not quite on top. 8" of separation between the uppers and lowers is good for the axle end.

You'll hafta learn me some of that control arm stuff. Sometimes it seems like it should be simple, sometimes it seems like dark arts.

I may just pick up a section of the 3" from you, put it on at some point, for preventative measures. Whats the cost per foot?

As for link stuff, its kinda voodoo at first, but its not too bad. The key is that, you can engineer it till the cows come home, but in the end, there are a few basic rules to follow, and the rest is dictated by the body/frame/axle to frame clearance.

If you are building a tube buggy, you can build it picture perfect by the book. If you have a body, you work within acceptable ranges.
